Arcane Sabotage (Su)

At 2nd level, a construct saboteur can user her arcane prowess to hinder constructs.

Whenever she uses Arcane Strike to attack a construct, she can activate one of the following sabotage abilities that she has gained. She gains one sabotage ability at 2nd level and can thereafter select any sabotage ability in place of a rogue talent. The DC for any sabotage ability that requires a saving throw is 10 + half the construct saboteur’s level + the construct saboteur’s Intelligence modifier.

Diminish Senses: A jolt of energy overwhelms the construct’s senses. The construct is blinded for 1 round. A construct saboteur can forgo dealing sneak attack damage to extend the duration of the blindness by 1 round for every 2d6 points of sneak attack damage forgone in this way. A construct can negate this effect with a successful Will save.

Magic Vulnerability: A field of energy enshrouds the construct, disabling its immunity to magic for 1 round.

Overwhelming Jolt: A sudden burst of power moves over the surface of the construct, giving it the staggered condition for 1 round. A construct can negate this effect with a successful Will save.

Slowing Pulse: A surge of slowing energy ripples through the construct, reducing its speed by 5 feet for a number of rounds equal to the construct saboteur’s Intelligence modifier. A construct saboteur can forgo dealing sneak attack damage to reduce the construct’sspeed by an additional 5 feet for every 1d6 points of sneak attack damage forgone in this way. This ability cannot lower a construct’s movement speed below 5 feet. A construct can reduce the duration of this effect to 1 round with a successful Reflex save.

Dismantling Strikes (Ex)

At 3rd level, a construct saboteur ignores the first 2 points of DR or hardness when attacking constructs. This value increases by 2 every 3 levels after 3rd, to a total of 12 points of DR or hardness ignored at level 18.
